A family of five was displaced after a fire that started in an SUV spread to their house early Friday, a Gwinnett County fire official said.

Firefighters responded shortly after 2 a.m. to the house in the 400 block of Thornbush Trace in Lawrenceville, spokesman Justin Wilson said in a news release.

A fire that started in the vehicle’s engine compartment went to the garage, then moved into the attic and broke through the roof over the garage, Wilson said.

A woman in the house saw the SUV on fire, then went back in the house and evacuated her three children, according to Wilson.

“Smoke alarms inside the home did not activate due to the location of the fire,” Wilson said.

Crews had the fire under control by 3 a.m.

No family members were injured. A firefighter sustained a minor injury.

The American Red Cross was contacted to provide assistance for the family, Wilson said.
